Typical data and test results for mechanical properties, deposit, or electrode composition and other properties were obtained from a weld produced and tested according to prescribed standards and should not be assumed to be the expected results in a particular application or weldment. Actual results will vary depending on many factors, including, but not limited to, weld procedure, plate chemistry and temperature, weldment design, and fabrication methods. Users are cautioned to confirm by qualification testing, or other appropriate means, the suitability of any welding consumable and procedure before use in the intended application.

  • Shear blades
  • Hot-punching dies
  • Wobller ends
  • Large cog-wheels
  • Plough shares
  • Rollers
  • Caterpillar treads
  • Rail ends and crossing
  • Preheat at 150ºC and over
  • In the case of multi-layer build-up welding or hardenable steel welding, underlay with low hydrogen type electrode (N-7016 or N-8016)
  • Dry the electrodes at 300-350ºC for 30-60 minutes before use
